Asia’s integration has been reshaping the global economic landscape. The emerging economies in East and Southeast Asia (grouped together as emerging East Asia) now account for about 25% of total global trade and 21% of global GDP, compared with about 10% and 5.8%, respectively, in 1985.
The idea that emerging East Asia is economically independent of shocks in major industrial countries is sometimes called the “decoupling hypothesis.” It’s based on the observation that the region’s sustained high growth in the early 2000s was seemingly unaffected by the ups and downs of major advanced economies. Emerging East Asia’s economic performance has been solid despite visible slowing in most advanced economies since the global financial crisis. This performance has been underpinned by dynamic growth in the People’s Republic of China (PRC).
Intraregional trade growth makes East Asia more resilient
The region’s high reliance on exports has been accompanied by a significant diversification of its export base: the G3 economies (the EU, Japan and the US) collectively accounted for 29% of emerging East Asia’s total exports in 2015, down from almost 50% in 1990. At the same time, the share of intra-regional trade in emerging East Asian economies’ total exports has risen dramatically. The PRC, in particular, now accounts for around 30% of intraregional exports. Strong growth in intraregional trade—including with the PRC—could constitute evidence for emerging East Asia’s greater resilience to cyclical fluctuations in the major extra-regional trading partners.
Emerging East Asia still vulnerable to external shocks
But changing demand conditions in the world’s major economies—particularly the US—still seem to represent a dominant driver behind East Asia’s export growth. Underlying this strong linkage between emerging East Asia’s growth and old industrial country growth is the nature of intra-Asian trade: the final output is often destined for markets outside the region. The growth of intra-regional trade share in total emerging East Asian exports does not automatically imply its independence from an external demand shock. Emerging Asian exports remain highly sensitive to economic shocks from outside the region.
As the region’s main production base and at the center of this growing intra-industry and intra-regional trade, the PRC is driving a change. The PRC has recently emerged as a major importer of primary commodities, while processed intermediate and capital goods, rather than consumer goods, are leading its exports. Recent research suggests that the PRC increasingly internalizes the manufacturing input supply in the global value chain. It also exports a large and growing share of capital goods, suggesting that Chinese manufacturing production has become more sophisticated and higher value-added.
Economic interdependence between PRC, rest of Asia has increased
Strong trade and foreign direct investment linkages can be channels for transmitting economic shocks. As the PRC has emerged as an important hub for intra-industry and intra-regional trade and investment in Asia, it is likely that economic interdependence between the PRC and the rest of Asia has also increased.
Region not (yet) fully decoupled from the West
Business cycle synchronicity might increase during crisis periods because the economies are more exposed to common shocks. But shocks that originate in one economy could also transmit to others. Our findings also support the growing importance of a regional component—especially of the PRC—in business cycle synchronicity.
Intra-regional trade and financial linkages are indeed strengthening, and the PRC’s moving up in the global value chain may lead to a more independent source of global growth. The progress of regional trade, financial integration and regional institution building—especially in Asia—could also facilitate business cycle synchronization more at regional than global level.
PRC moving up global value chain may lead to more independent global growth
For now, however, Asia does not yet appear to be decoupling from the world economy yet. The expansion of Asia’s trade and investment links is still driven by the region’s global demand-linked production network. Emerging East Asia has become more, not less integrated with the global economy, and as a result the impact of a global shock, whether related to trade or financial markets, has become greater. Eventually, the key to Asia’s decoupling from the world will be successful rebalancing of the Chinese economy, leading to greater and more autonomous demand in Asia.
